TL;DR
Breathing in hydrogen-rich gas before exercise can help reduce feelings of fatigue and improve recovery from intense workouts.
Key Finding
Inhaling hydrogen-rich gas before intense cycling exercise significantly reduced perceived fatigue and exertion while improving the body's ability to neutralize harmful free radicals (hydroxyl radicals) and clear lactate from the blood.
Summary
Researchers tested whether breathing hydrogen-rich gas before intense exercise could reduce fatigue in 24 healthy men. After inhaling either hydrogen-rich gas or regular air for 60 minutes, participants cycled at high intensity until exhaustion. Those who breathed hydrogen-rich gas reported feeling less tired, had lower perceived exertion (how hard the exercise felt), maintained better cycling performance in the final 30 seconds, and showed improved markers of oxidative stress (cellular damage from intense exercise) compared to the placebo group.
Practical Takeaway
This small human study suggests that pre-exercise hydrogen inhalation may help reduce exercise fatigue and support recovery markers, though the findings are limited to healthy young men doing high-intensity cycling. More research is needed to determine if these benefits apply to other populations, exercise types, or real-world athletic settings, and whether the effects are large enough to matter practically.
Abstract
Hydrogen, as an antioxidant, may have the potential to mitigate fatigue and improve selected oxidative stress markers induced by strenuous exercise. This study focused on previously unexplored approach of pre-exercise inhalation of hydrogen-rich gas (HRG). Twenty-four healthy adult men first completed prelaboratories to determine maximum cycling power (Wmax) and maximum cycling time (Tmax). Then they were subjected to ride Tmax at 80% Wmax on cycle ergometers after inhaled HRG or placebo gas (air) for 60-minute in a double-blind, counterbalanced, randomized, and crossover design. The cycling frequency in the fatigue modelling process and the rating of perceived exertion (RPE) at the beginning and end of the ride were recorded. Before gas inhalation and after fatigue modeling, visual analog scale (VAS) for fatigue and counter-movement jump (CMJ) were tested, and blood samples were obtained. The results showed that compared to placebo, HRG inhalation induced significant improvement in VAS, RPE, the cycling frequency in the last 30 seconds, the ability to inhibit hydroxyl radicals, and serum lactate after exercise (p < 0.028), but not in CMJ height and glutathione peroxidase activit. In conclusions, HRG inhalation prior to acute exercise can alleviate exercise-induced fatigue, maintain functional performance, and improve hydroxyl radical and lactate levels.
